Abstract
An apoptosis inductor is formed of an anthocyanin-containing extract obtained from a potato containing anthocyanine in the skin and flesh thereof. The potato is a potato of cultivated species, such as Solanum tuberosum ssp. andigena L. and S. phureja Juz. et Buk., or of hybrid species based on the cultivated species.
Claims19
A method for inducing gastric cancer cell apoptosis comprising a step of administering an anthocyanin-containing extract obtained from a potato containing anthocyanin in its skin and flesh to a subject in need thereof, wherein an acid or an acid alcohol is used as an extracting solvent;
- the extracting solvent contains not less than 1% of table salt;
- and a pH of the extracting solvent is not more than 3.0 and/or a temperature of the extracting solvent is not higher than 10° C.
A method for inducing gastric cancer cell apoptosis, comprising:
- extracting a potato containing anthocyanin in its skin and flesh with an extracting solvent comprises an acid or an acid alcohol, wherein the pH of the extracting solvent is not more than 3.0 and/or the temperature of the extracting solvent is not higher than 10° C. to produce an extract containing anthocyanin, and
- administering the extract to a subject in need thereof.
In a process for inducing gastric cancer cell apoptosis in a subject in need thereof, the improvement comprising obtaining an extract containing anthocyanin by extracting a potato containing anthocyanin in its skin and flesh with an extracting solvent comprising an acid or an acid alcohol, wherein the pH of the extracting solvent is not more than 3.0 and/or the temperature of the extracting solvent is not higher than 10° C. and administering the extract to the subject.
A method for inducing gastric cancer cell apoptosis comprising administering an anthocyanin-containing extract obtained from a potato containing anthocyanin in its skin and flesh to a subject in need thereof, wherein an acid or an acid alcohol is used as an extracting solvent;
- the acid is lactic acid or acetic acid;
- and a pH of the extracting solvent is not more than 3.0, and/or a temperature of the extracting solvent is not higher than 10° C.
